TIE Toa MINE TRACKS. j

Application led July 28,

vthat portion of the mine from which coal has been excavated.

One of the objects of this invention is to provide a very simply constructed tie which may be made of steel and by which the rails are securely clamped in place, the tie being so constructed that the rail clamps may be readily detached from the tie to permit the removal of the rails. Y

A further object is to provide a tie of this description which is adapted for use with plain rails or at joints, and in the latter case is adapted to be used as a lug joint tie or with bolts at the joint as desired.

A still further object is to provide a construction of this character which will permit one of the rail clamps to be readily detached or put in place to permit the ready detachment of the rail and thereby permit the ready re-arrangement of the tracks.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a top plan view of a mine track tie constructed in accordance with my invention, one of the rails being partly in section;

Figure 2 is a section on the line 2 2 of Figure 1;

Figure 3 is an elevation of the construction shown in Figures 1 and 2;

Figure 4f is a perspective view of the clamp 17;

Figure 5 is a fragmentary perspective view of the flange 18, showing the manner in which the studs 27 are formed;

Figure 6 is a fragmentary perspective view showing another manner of constructing the plate 17;

Referring to these drawings, 10 designates a tie which is preferably of metal U-shaped in cross section to provide the side flanges 11. Obviously this tie may have any suitable 1923. Serial No. 654,396.

length.f Attached to the ends of the tie are the plates 12. These plates may bel riveted to the tie by means of the rivets 13. These plates rest flat against the` tieat their outer ends andthen incline upward and forward, as at 14. The innerr end of the plateis upwardly angled or extended, as at 15, and the sides vof the plate are upwardly angled or extended, as at 16, toform abutments against lwhich the transverse member or flange 15 ears.

This flange is preferably longer thanv the distance between the upwardly extendin g abutments 16 so as to extend preferably slightly beyond the tie itself. It is obvious,

however, that this is not a necessary feature.

The plate 12 with its flanges 15 and 16 might be cast in one piece or formed of sheet metal. y

Ooacting with these clamping members 12 are clamping members 17 These are each formed of a plate of metal angularly bent at -its end, as at 18, to confront the portion 15 of the plate 12. Side flanges 19 are bentup from the plate 17 and. abut at their ends against the flange 18 to support the same and strengthen the plate. Adjacent its end vrermote from the flange 18 the plate is formed with a transversely extending depression 20, and extending longitudinally through the plate is a slot 21 which intersects this depres` sion. The tie 10 is formed inward of each of the'rail clamps with a transversely ex- Y thus locking the clamping lmember 17 sev curely in place.` This clamping member 17 is also formed so that when it is clamped in place the flange of the rail Al will fit beneath the plate 17. v

In Figure 1, T have shown one end of the tie as being formed with the clamping plates 17 and 12, as before described, but l have also illustrated the flange 15 at the other end as formed at is ends with openings 26 and have shown the flange 18 as provided with parallel studs 27 which extend through these openings 26 and through openings in the adjacent ends of the two rails, thus constituting a joint clamp. Thus in a single tie one end of thetiema'ybeformed to engage andv hold the joint closed and the opposite end lof the tie may be formed with clamps which will engage the intermediate'portion of a rail. Obviously ties may be formed which at both ends will engage the intermediate portion of the rail if desired. y

l do not Wish to be limited to the use of the studs 27 inconj'unction with the 'perforationsf26 'in plate p15, but I may use, as illustrated in'ligure 6, azplate 17, thev extremities of the flange 18 being formed with openings 28 which will confront'the openings 26'.and; through whichbolts may be passed to: hold the. clamps in engagement with the'abutting :railsr at the rail joint. l have illustrated 'in Figure 1L the studs 27 as being formed as: shown in Figure 5, that is by lugs projecting longitudinally from the flange 18, the-se lugs being bent into a cylindrical form so as to pass through the openings :26. Obviously l do not wish to be limited to this.

I' claim' k1. A metallic tie of the character described `having downwardly extending` side flanges, .the face of the tienta-distance from an end being provided jwith 'a transversely depressedportionand an upstanding eye belneath whichv the depressed portion extends, Ya rail clamping member attached to the end of the tie 'and vhaving a'vertical portion `adapted to bear against the web of a rail, a

clamping `member including a vertical portion adapted to confront the vertical portion of the .first named clamp and having a base adapted" to'v rest upon the tie, this base having a'transversely depressed portion, a slot intersr'ecting said depressed portion and adapted` to receive the eye, and a locking Lmember adapted to pass lacross said de'- 'p're'ssedfportion of the clamping member and beneath said' eye. 2. A metallic tie of the character described `having spaced from oneend a vtransversely `extending depressed portion and having struck upfrom the tie fan upwardly `extending eye intersecting said depressed portion,"a vrail clampiiig member attached to `one end ofthe'tie' and having a vertical f 'formed with atransversely extending depressed? portion adapted `to fit Yin the depressed portion of'the Vtie and with a longitudinally extending slot adapted to receive said eye, the transversely extending flange of the last named clamp -being 'formed at its ends witlr means for engagement with abutting rails and with the apertures of the first named transversely extending portion.

3. A metallic tie of the character described having spaced from one end a transversely extending depressed portion and having struck up from the tie an upwardly extending eye intersecting said depressed portion, a rail clamping member attached to one end of the tie and having a vertical flange extending transversely of the tie, the ends of the flange being perforated, a second clamping member having a base and an upwardly extending flange, the base being formed with a transversely extending depressed port-ion adapted to nt in the depressed portion of the tie and with a longitudinally extending slot adapted to receive said eye, the transversely xtending flange of the last named clamp being formed with longitudinally extending studs adapted to pass through apertures in abutting rails and through the apertures in the first named transversely extending flange.

Ll-.YA rail tie of the character described comprising a sheet metal body having laterally depending flanges, rail clamps at the ends of the tie,`each clamp comprising a plate riveted to the tie, the end of the plate being upwardly bent to forni a transversely extending flange and the sides of the plate being upwardly bent to form abutting flanges, the face of the tie inward of said rail clamps being formed with transversely extending depressed portions and with longitudinal slots crossing said depressed portions, the material of said slots being bent upward to form eyes, and rail clamps opposed to the first named clamps, each consisting of a plate of sheet metal, the end of the plate being upwardly bent to form a transverse flange adapted to confront the first named transverse flange, the end of the plate remote from said flange being transversely depressed and longitudinally slotted, the slot being large enough to receive said eye, and a transverse pin adapted tobe inserted through said eye and to rest in thedepressed portion of' the plate and hold the plate in place.

In testimony whereof l hereunto affix my signature.
